Description
본 고안은 시멘트보드 등의 경질소재를 부착하는 과정에서 이용되는 스크류에 관한 것으로, 특히 스크류의 몸체부에 별도의 기구를 체결품의 안쪽으로 머리부를 진입시킴과 더불어 스크류의 체결에 따른 작업하중을 최소화시킬 수 있도록 된 경질보드고정용 스크류에 관한 것이다.The present invention relates to a screw used in the process of attaching a hard material such as a cement board, in particular to the head of the screw into a separate mechanism into the interior of the fastener, and minimize the work load due to the screw tightening It relates to a hard board fixing screw that can be made.
일반적으로, 스크류는, 물품을 원하는 장소에 부착 및 고정하는 과정에서 이용되는 체결기구의 일종으로서, 이러한 스크류는 금속재질로 형성되면서 십자 또는 일자홈 또는 다각홈이 형성된 머리부와 이 머리부의 하부측에 일체로 형성되면서 그 둘레면에 나선홈이 형성된 몸체부로 이루어진다.In general, a screw is a kind of fastening mechanism used in attaching and fixing an article to a desired place. The screw is formed of a metal material and has a head or cross-shaped groove or a polygonal groove, and a lower side of the head. It is formed integrally with the body portion formed with a spiral groove on the circumferential surface thereof.
여기서, 스크류로서 종래에는 경질의 재질을 관통할 수 있도록 열처리된 제품이 많이 개발되어 사용되고 있지만, 현대에는 전동드릴 등과 같은 제품의 발전으로 인하여 스크류의 강도가 약하더라도 경질의 제품을 관통할 수 있기 때문에 직결스크류를 이용하여 물품들을 고정시키게 된다.Here, as a screw, in the past, many heat-treated products have been developed and used to penetrate a hard material. However, due to the development of a product such as a power drill, in modern times, even though the strength of the screw is weak, it can penetrate a hard product. The articles are fixed using a direct screw.
그러나, 전동드릴에 의해 경질재료 즉, 시멘트보드나 합성보드를 체결하는 과정에서 스크류가 외력에 의해 빠른 속도로 파고들면서 그 구멍의 크기 만큼 보드가 주위로 밀려나 파손됨은 물론 구멍의 불필요한 확장으로 인해 부착물과의 원하는 결속력을 얻기 어려운 단점이 있었다.However, in the process of fastening the hard material, that is, cement board or composite board by a power drill, the screw penetrates rapidly by external force and the board is pushed around and damaged by the size of the hole. There was a drawback that it was difficult to get the desired cohesion.
그리고, 시멘트보드나 합성보드에 체결된 스크류의 머리부가 보드안으로 진입할 수 없도록 구성되어 외부로 돌출되므로 또다른 보드를 부착할 때 밀착력이 저하될 우려가 있을 뿐만 아니라 바닥면에 체결된 스크류의 머리부가 돌출되는 경우 보행자에게 불편함을 초래하는 것이다.In addition, since the head of the screw fastened to the cement board or composite board is configured to prevent entry into the board and protrudes outwards, there is a possibility that the adhesion force is lowered when another board is attached, and the head of the screw fastened to the bottom surface. If the protrusion protrudes, it causes inconvenience to pedestrians.
따라서, 스크류의 체결지점에 머리부가 진입할 정도의 깊이 만큼 보오링작업을 수행한 후 이차로 스크류의 체결작업을 수행하므로, 스크류의 체결에 따른 작업성이 저하될 뿐만 아니라 작업공정수 및 작업하중이 증대되어 제반 부대비용이 상승되는 문제점이 있었다.Therefore, after the boring operation is performed as much as the depth of the head to enter the fastening point of the screw to perform the second screw fastening work, not only the workability due to the fastening of the screw but also the number of work processes and work load There was a problem that the increase in all the additional costs.
이에, 본 고안은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 스크류의 몸체부에 별도의 기구를 체결품의 안쪽으로 머리부를 진입시킴과 더불어 스크류의 체결에 따른 작업하중을 최소화시킬 수 있도록 된 경질보드고정용 스크류를 제공하는 데에 그 목적이 있다.Thus, the present invention was devised to solve the problems as described above, so that a separate mechanism into the body of the screw enters the head into the interior of the fastener to minimize the work load due to the fastening of the screw. It is an object of the present invention to provide a hard board fixing screw.

먼저, 본 고안에 따른 구성요소 중 스크류(100)의 머리부(110)와 몸체부(120)는 공지기술과 기능상 동일하므로 자세한 설명은 생략하고, 다만 머리부(110)에 톱날부(30)가 일체로 형성되면서, 몸체부(120)에 드릴부(10)와 칼날부(20)가 일체로 형성된 것에 차이점이 포함된다.First, the head 110 and the body portion 120 of the screw 100 of the components according to the present invention are the same in function and known technology, so the detailed description is omitted, but the saw blade portion 30 to the head 110 While integrally formed, the difference between the drill portion 10 and the blade portion 20 is integrally formed on the body portion 120.
그리고, 드릴부(10)는, 몸체부(120)의 선단부 바람직하게는, 선단부의 일측에 돌출되게 형성된 것으로서, 상기 스크류(100)의 회전방향을 따라 날부분이 형성되도록 배치시킴이 바람직하다.In addition, the drill portion 10, the tip portion of the body portion 120, preferably formed to protrude on one side of the tip portion, it is preferable to arrange so that the blade portion is formed along the rotational direction of the screw (100).
그리고, 칼날부(20)는 몸체부(120)의 둘레면 양측면에 나란하게 돌출되게 형성된 것으로서, 몸체부(120)의 둘레면에서 가능한 1/2정도 이하의 지점에 형성시킴이 바람직하다. 이때, 칼날부(20)가 구성된 몸체부(120)의 전체폭은 머리부(110)에 비해 약간 크기로 형성시킴이 바람직하다.And, the blade portion 20 is formed to protrude side by side on both sides of the circumferential surface of the body portion 120, it is preferable to form at about 1/2 or less as possible from the circumferential surface of the body portion 120. At this time, the overall width of the body portion 120 is configured blade portion 20 is preferably formed to be slightly larger than the head portion 110.
그리고, 톱날부(30)는, 머리부(110)의 하면에 일정간격을 두고 돌출되게 형성된 것으로서, 상기 스크류(100)의 회전방향을 따라 날부분이 형성되도록 배치시키고 다수개 형성시킴이 바람직하다.In addition, the saw blade portion 30 is formed to protrude at a predetermined interval on the lower surface of the head 110, it is preferable to arrange so as to form a plurality of blades are formed along the rotational direction of the screw 100. .
이하, 본 고안에 따른 작용을 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described.
먼저, 스크류(100)를 이용하여 경질보드 등을 고정하려는 경우, 일단 체결소재(200)의 적정지점에 스크류(100)의 드릴부(10)를 맞댄 상태에서 머리부(110)의 홈에 공구를 삽입하여 일방향으로 회전시킨다.First, in the case of fixing the hard board, etc. by using the screw 100, the tool in the groove of the head 110 in a state in which the drill portion 10 of the screw 100 is brought into contact with the appropriate point of the fastening material 200 once. Insert it to rotate in one direction.
이렇게 하면, 드릴부(10)에 의해 체결소재(200)가 천공되어 스크류(100)가 점점 더 진입하는 상태로서, 도 2a에서와 같이 스크류(100)의 칼날부(20)가 체결소재(200)의 표면에 접촉하게 되는 것이다.In this case, the fastening material 200 is drilled by the drill part 10 and the screw 100 is gradually entering. As shown in FIG. 2A, the blade part 20 of the screw 100 is fastening material 200. ) Is in contact with the surface.
이로 인해, 칼날부(20)의 회전에 의해 체결소재(200)의 표면부에 일정깊이로 파내어진 오목홈(40)이 형성되는 것이다.For this reason, the concave groove 40 is excavated to a predetermined depth by the rotation of the blade portion 20 to the surface portion of the fastening material 200 is formed.
이어서, 체결소재(200)의 천공부에 스크류(100)가 점점 더 진입하는 경우, 칼날부(20)가 파괴되어 제거되고, 2b에서와 같이 스크류(100)의 톱날부(30)가 체결소재(200)의 오목홈을 파고 들어가는 것이다.Subsequently, when the screw 100 enters the perforation part of the fastening material 200 more and more, the blade part 20 is destroyed and removed, and the saw blade part 30 of the screw 100 is fastened as in 2b. It is to dig into the recess of 200.
따라서, 체결소재(200)의 표면부에 형성된 오목홈(40)에 스크류(100)의 머리부(110)가 수납되어 외부와의 간섭이 방지되는 것이다.Therefore, the head 110 of the screw 100 is accommodated in the concave groove 40 formed in the surface portion of the fastening material 200 to prevent interference with the outside.
이상에서와 같이 본 고안에 따른 경질보드고정용 스크류에 의하면, 체결소재의 표면부에 스크류의 머리부가 수납되어 체결상태를 유지하므로, 머리부의 돌출로 인하여 발생하는 밀착력 저하가 방지되어 체결력이 극대화됨은 물론 외부와의 간섭이 방지되어 편리성이 제공되는 효과가 있는 것이다.As described above, according to the hard board fixing screw according to the present invention, since the head of the screw is accommodated in the surface portion of the fastening material to maintain the fastening state, the deterioration of the adhesion caused by the protrusion of the head is prevented to maximize the fastening force Of course, there is an effect that convenience is provided by preventing interference with the outside.
또한, 체결소재의 높이보다 스크류의 머리부가 깊이 체결되어 그 삽입부분을 체결소재와 유사한 색상 및 재질로 커버할 수 있어 공간을 확보할 수 있음은 물론 외관미를 향상시킬 수 있는 효과가 있는 것이다.In addition, the head of the screw is fastened more than the height of the fastening material can cover the insertion portion with a color and material similar to the fastening material to secure space and have the effect of improving the appearance.
그리고, 스크류의 체결과정에서 보오링작업 등의 추가공정이 필요없어지므로, 스크류의 체결에 따른 작업성이 극대화됨은 물론 작업공정 및 작업하중이 최소화되어 각종 부대비용이 절감되는 효과가 있는 것이다.In addition, since an additional process such as boring work is not required in the screwing process, the workability due to the screwing is maximized as well as the work process and the work load are minimized, thereby reducing various additional costs.
